2. Input excessive voltage in the DCV range.
• Settings on module under test: 1 V range or less, measurement interval of
500 msec
• Apply voltage between I, A and B, C terminals on channels 1 through 6.
• Apply ±20 V to each for ten seconds and confirm that the instrument
operates normally.
3. Input an excessive voltage in the resistance range.
• Settings on module under test: 20 Ω, measurement interval of 500 msec
• Short the I, A, B, and C terminals on channels 1 through 6 and apply a
voltage to both ends.
• Apply ±10 V to each for one minute and confirm that the instrument operates
normally.
* Abnormalities refers to excessive current or emissions of light or smoke.
2.6.4 ID Check
This test confirms whether the module is correctly identified when module information is
obtained from the MX100, MW100, or equivalent.
Procedure
Power cycle the instrument and confirm that the module ID is recognized correctly.
